Abstract
This invention relates to a composite keel, characterized in that it comprises the bar keel and lump keel, wherein on the lump keel is arranged a strip main bar, and the side wall of the main bar is arranged the prominence; on the lump keel surface near the main bar set at least one assistant bar parallel to the main bar; behind the lump keel is arranged a beard corresponding to the bar keel, and the lateral of the beard is arranged vertically or inside, outside incline, on the surface is arranged a barb; the lateral of the bar keel is correspond with the beard, and on the surface of the bar keel is also set a barb which is fitted to the barb set in the beard. Said keel can lock the longitudinal joint of two adjacent boards, and it is suitable to mating use with the floor, wall plate and the ceiling.
Description
Technical field
The present invention relates to common joists, relate in particular to a kind of being suitable for and floor, wallboard and the matching used combined joist of ceiling.
Background technology
What the tradition wood floor joist adopted usually is lumps of wood bar, and with the batten nail on the ground, wood flooring is followed closely on lumps of wood bar again during use, so not only install complicated, be easy to destroy the structure in house, but also can make the stress of wood flooring excessive, cause the wood flooring distortion easily.Dismounting can not be repeated in floor after the installation, and maintenance is inconvenient.
Summary of the invention
The objective of the invention is in order to solve the deficiency that the above-mentioned background technology exists, it is easy for installation, quick to propose a kind of wood flooring, wallboard and ceiling of making, and installation quality is good, and the combined joist that can not be out of shape, warps makes it be convenient to dismounting, maintenance after installation.
For achieving the above object, the present invention adopts following technical scheme: combined joist, it is characterized in that it is made up of strip keel and block keel, be provided with a strip master muscle at block top of keel, the sidewall of this main muscle is provided with protrusion, block keel surface in these main muscle both sides, every side are provided with an auxiliary muscle parallel with main muscle at least; Be provided with the groove that can match with the strip keel at the block keel back side, these groove two sides are vertically or outwards, be in tilted layout inwards, the surface is provided with barb, and strip keel two sides are corresponding with block keel groove, and its surface is provided with the barb that can cooperate with groove two sides barb.
The cross section of described main muscle is T shape or Γ shape, the perhaps combination of T shape and T shape, the perhaps combination of T shape and Γ shape, the perhaps combination of Γ shape and Γ shape.
Vertical direction is provided with the nail hole in the strip keel.
In such scheme, it is vertical with strip master muscle to be arranged on the groove that can match with the strip keel at the block keel back side.
Cooperate by the negative and positive groove each other with the matching used plate of the present invention (floor or wallboard or ceiling), be provided with the groove that matches with above-mentioned main muscle at the vertical or horizontal seam crossing of adjacent two plates, this groove lays respectively on the vertical or horizontal side of adjacent two plates, form by adjacent two plates splicing back, and parallel with the jointing line of this splicing, on the plate of these groove both sides, be provided with the groove that can hold auxiliary muscle with auxiliary muscle corresponding position, block keel surface.
Keel of the present invention are installed on longitudinal seam place between the piece plate.It is easy for installation, need not during installation to need not boring with glue, nail and clamping plate, and saving of labor, material-saving, technology is simple, and is quick for installation, do not have noise, dust and the rubbish of installation, convenient transportation.Keel of the present invention can pin adjacent two interplate longitudinal seams, and making between plate and the plate does not have the gap, and plate can not be out of shape yet, warp, and has improved installation quality greatly.Be convenient to dismounting, maintenance after the installation.The present invention is suitable for the floor of various materials, comprises consolidated floor, all kinds of composite floor board and multi-layer floor, wood flooring, bamboo floor etc., can with the supporting use of floor, wallboard and ceiling.

The specific embodiment
Referring to figs. 1 through Fig. 4.The present invention is made up of strip keel 4 and block keel 1, described block keel 1 are rectangular, be provided with the main muscle 2 of the combination of the combination of combination that a cross section is T shape or Γ shape or T shape and T shape or T shape and Γ shape or Γ shape and Γ shape on block keel surface on one side, see Fig. 2, Fig. 3.In the block keel surface of these main muscle 2 both sides, every side is provided with one at least, and the parallel auxiliary muscle 3 of two or many and main muscle 2 also can be set.The cross section of auxiliary muscle 3 can perhaps be a raised boss for shapes such as T shape, Γ shape, rectangle, triangle, polygons, and the surface of this raised boss is an arc.
Be provided with the groove 5 that can match with strip keel 4 at block keel 1 back side, these groove 5 two sides are vertically or outwards, be in tilted layout inwards, the surface is provided with barb 6, strip keel 4 two sides are corresponding with block keel groove 5, its surface is provided with the barb 7 that can cooperate with groove two sides barb 6, is used for block keel 1 are fixed in strip keel 4.Utilize the nail hole 8 in the strip keel 4 strip keel 4 can be fixed on the ground that needs the installation plate, on the metope or on the ceiling.
The direction that is arranged on the groove 5 that can match with strip keel 4 at block keel 1 back side is vertically vertical with main muscle 2, is used for longitudinal seam place installation between the plate.
The present invention can be used for longitudinal seam place installation between the piece plate.Mounting structure is seen Fig. 5, Fig. 6 and Fig. 7.
